Merged Archive (ma)

In a typical live use case, an event is always published from one (primary) encoder and delivered using an HDS player to the end users. It is highly recommended to use a backup encoder in case there are issues with the primary broadcast, for example, connectivity issues or hardware failure.

Available values are “on” and “off.” The default value is “off.” This query string
when set to “on” enables end-users to The ma query string is
currently available only for HDS and not for HLS. In case of HLS, since the
playback is controlled completely by the client, the primary content would always
be played unless there is an error in getting a primary playlist. In this case,
the backup would be tried.

In case when the primary and backup feeds do not have the same bitrates published, the "ma" query string does not work and causes a playback failure.
